A commercial refrigeration system receives data from a plurality of compressors in a compressor rack, and uses the data to model a steady state amp draw for each of the compressors in the compressor rack. The system receives additional data from the plurality of compressors, and determines a steady state amp draw for each of the compressors from the additional data. The system then compares the amp draw from the additional data with the steady state amp draw model, and identifies a compressor fault based on the comparison of the steady state amp draw from the additional data with the steady state amp draw model.
